Gall bladder (GB) may be found in a variety of abnormal positions. Most of them are due to arrested development of embryonic growth at different stages. A 63-year-old female patient was admitted to our radiology unit for magnetic resonance imaging (MRI) of the liver for the lesions identified in abdominal ultrasonography (US) and computed tomography (CT). MRI showed that there was a lobulated heterogenous mass in the left lobe of the liver and a smaller one in the right lobe of the liver with the same appearance. The inferior pole of the liver was located in the pelvic space, and the GB, which contained sludges and stones, was lying down to the upper pelvic space. Hepatic masses were considered to be hemangiomas, and GB was diagnosed as ptotic GB with luminal sludge and stones. In this case, especially, MR imaging helped the surgeon to plan a proper approach to the GB in abnormal localization.

Synovial sarcoma (SS) primarily occurs in the para-articular soft tissue of the lower extremities in young adults and it is extremely rare in the prostatic region. We report a case of a 46-year-old man who presented with urinary retention. Pelvic ultrasound (US) examination, computed tomography (CT), and magnetic resonance imaging (MRI) demonstrated an 8.5 cm mass that appeared to originate in the prostatic fascia of the right lobe. Preoperative prostatic ultrasound transrectal needle biopsy revealed mesenchymal neoplastic tissue. Patient underwent surgery. The final pathologic findings were consistent with the diagnosis of monophasic synovial sarcoma.

Abstract A 54-year-old man with a right hemiparesis was found to have an intrasellar intercarotid communicating artery associated with agenesis of the right internal carotid artery. Magnetic resonance imaging (MRI) studies demonstrated the spatial relationship of the anomalous artery to the surrounding structures, thus suggesting an embryonic enlargement of the capsular artery as a source of this anomalous artery.

Objective. To establish the diagnostic role of ASL-perfusion of the liver in magnetic resonance imaging (MRI) in assessing the risk of portal hypertension in patients with viral hepatitis. Materials and methods. 109 patients with viral hepatitis were examined, including 69 (63.3 %) men and 40 (36.7 %) women, the average age of patients was 49.0 ± 2.3 years. All subjects (n = 109) underwent abdominal ultrasound with doppler vascular examination and clinical elastography, ASL-perfusion of the liver with MRI with an assessment of the volume of hepatic blood flow (HBF, ml/100 g/min).Results. The highest diagnostic and prognostic significance of ASL-perfusion for the liver is a targeted study of changes in the right lobe: for the right lobe, AUROC = 0.886 (95 % CI: 0.799–0.889); for the left, AUROC = 0.635 (95 % CI 0.627–0.641). The diagnostic and prognostic significance of ASLperfusion was evaluated in comparison with ultrasound with doppler vascular examination: AUROC = 0.991 (95 % CI: 0.880–0.993); AUROC = 0.801 (95 % CI: 0.776–0.804), respectively. The quantitative and qualitative characteristics of ASL – liver perfusion were evaluated.Conclusion. When performing ASL-perfusion of the liver, MRI should evaluate quantitative and qualitative criteria. Criteria for the prognosis of portal hypertension according to ASL- perfusion in MRI in patients with viral hepatitis: HBF 131–160 ml/100 g /min, red card – very high risk, HBF = 161–185 ml/100 g/min, red card – high, HBF = 40–130 ml/100 g/min, mixed card – medium; HBF = 131–160 ml/100 g/min, blue card-low risk (r = 0.883).

In vivo dynamic changes in the interosseous membrane (IOM) during forearm rotation were studied using magnetic resonance imaging (MRI). The right forearms of 20 healthy volunteers were examined in five different rotational positions. Axial slices were obtained at the proximal quarter, the middle and the distal quarter of the forearm. The changes in shape of the IOM during rotation were observed in an axial MR plane. For each image, we measured the interosseous distance and the length of the interosseous membrane. Images of the tendinous and membranous parts of the IOM could be differentiated by thickness. There were minimal dynamic changes in the tendinous part on the MRI while the membranous part showed numerous changes during rotation. The interosseous distance and the length of the interosseous membrane were maximum from a neutral to a slightly supinated position. The tendinous part is considered to be taut during rotation to provide stability between the radius and the ulna, but the membranous part which is soft, thin and elastic, allows smooth rotation.

ABSTRACTWe report an unusual case of unilateral limb pseudo hypertrophy in a 21-year-old lady who developed progressive enlargement of the right calf followed by thigh in association with chronic leg pain. Magnetic resonance imaging (MRI) of the affected limb confirmed enlargement of various muscles. Electromyography revealed neurogenic features consistent with S1 radiculopathy. MRI of the lumbosacral spine showed tethered cord with a lipoma infiltrating multiple sacral roots. Our case illustrates that muscular pseudo hypertrophy may follow chronic denervation as a consequence of spinal neural compressive disease. The various mechanisms postulated for this distinct condition are outlined.

AbstractWe present our experience using the Clarion® magnetless multichannel cochlear implant with a woman profoundly deafened following bilateral acoustic neuromata as a consequence of neurofibromatosis 2 (NF2). The right neuroma had been previously removed without an attempt at neural preservation. On the left, however, a posterior fossa approach had been taken with the aim of preserving hearing. Although the left cochlear nerve appeared to be undamaged at the end of the operation, no hearing thresholds could be elicited on post-operative audiometry, because of damage either to the cochlear nerve or to the blood supply to the cochlea. Round window electrical stimulation subsequently produced a perception of sound, confirming that the cochlear nerve was capable of functioning and that a cochlear implant would be effective. Because she would need regular magnetic resonance imaging (MRI) to monitor existing and future NF2 lesions, it was decided to use a magnetless Clarion® implant, which has been shown to be MRI compatible. We report our experience of using the device in this case and discuss some of the issues related to the provision of cochlear implants to patients with NF2.

Paraspinal Abscess

Here presented is a case involving a 44-year-old man with a chief complaint of sharp lateral right-sided rib pain with notable radiation to the anterior portion of the thorax and minor radiation around the lateral back. The etiology of the pain and radiculopathy, which was initially attributed to a right-sided rib fracture, was later accurately credited to a paraspinal abscess discovered on a lateral X-ray of the thoracic spine. Subsequently, studies including Magnetic Resonance Imaging (MRI), Computed Tomography (CT), and bone scan all confirmed the diagnosis of a paraspinal abscess between the right lobe and its neighboring T9 and T10 vertebrae. The mass was biopsied and methicillin sensitive Staphylococcus aureus was isolated. Appropriate surgical and medical intervention was possible due to the early diagnosis of the abscess.

A 12-year-old pre-menarchal girl presented to our emergency department with acute urinary retention for last eight hours. She admitted having difficulty in micturition for last one month. She denied any other significant past medical or surgical history. During per urethral catheterization a non-tender lump which used to increase on Valsalva manoeuvre was noted in the perineum. Abdominal ultrasonography and magnetic resonance imaging (MRI) showed a large haematocolpos compressing the urethra. She underwent hymenotomy with evacuation of collected menstrual blood. Post procedure recovery was uneventful and she was able to pass urine with normal stream subsequently.

The multiseptate bladder is a congenital bladder anomaly that is very rare and often accompanied by other congenital abnormalities. This condition could result in intravesical obstruction and kidney failure in more serious conditions. A 3-year-old girl without any complaint was consulted by the Pediatric Surgery Department with postoperative cloacal type malformation anorectal (MAR) postero-sagittal anorecto-vagino-urethroplasty (PSARVUP) + sigmoidectomy. Magnetic Resonance Imaging (MRI) of the pelvis showed the appearance of four interconnected multiple fluid lesions. Cystoscopy was performed and found many septa with varied positions and forms. From the cystography during the operation, it was seen duplication of the right and left bladder. There was no further operative treatment in the field of urology because no urinary tract obstruction and normal renal function were found in this study.

<p class="abstract">Fibromatosis colli is a rare benign lesion characterised by a proliferation of fibrous tissue within the sternocleidomastoid muscle. There is a slight preponderance to affect males and it occurs more frequently on the right side of the neck. Here, we report a 6-week-old girl who presented with a swelling on the left side of her neck, opposite to usual tendencies. Ultrasonography reported a left sternocleidomastoid muscle tumour of unknown specificity. A magnetic resonance imaging (MRI) was needed to ascertain the final diagnosis of a left fibromatosis colli. She was managed conservatively and the condition resolved by the age of 1 year. In most cases, fibromatosis colli is reliably diagnosable with ultrasonography alone. MRI may be considered as an adjunct in situations where diagnostic doubts still persist.</p>
